Nutrition 1 Assessment Item 1: Short Answer Questions 1. Define what a nutrient is and discuss the difference between the major macronutrients. The human body uses nutrients for energy, growth and bodily functions. Nutrients come in different types, some that the body requires in smaller amounts and some that the body will need to take in a greater amount of. The nutrients that are required in larger amounts are called macronutrients. The three macronutrients consist of; Carbohydrates, Lipids…

vitamin C are especially fruits and vegetables, particularly citrus fruits such as oranges. Vitamin C has significant relationships with other nutrients. It contributes to the metabolism of certain amino acids such as phenylalanine and tyrosine which become hormones. The vitamin C can have a significant role in the metabolism of calcium and iron. It also protects the thiamine, riboflavin, folic acid, pantothenic acid, vitamin A and E from oxidation. It protects the brain and spinal cord from…

It is used within the first few minutes of all exercise, before there is adequate oxygen available at the muscles for aerobic metabolism. The anaerobic system is used when fast, powerful bursts of energy are required. There are two systems within anaerobic metabolism, these are; • The ATP-PC system • The lactic acid system. The anaerobic system would be most useful in explosive sports such as sprinting, GAA and swimming. Carbohydrates The role…

Chloroplast are found in plants, they are responsible for the metabolism of energy to produce food for plants by breaking down Carbon dioxide, water and sunlight through a process called Photosynthesis. Once Carbon Dioxide enters a plant through stomata pores in a plant, water is absorbed through the roots of a plant and sunlight captured by chlorophyll pigments inside the chloroplast which is actually inside the thylakoids. It 's the russian doll complex., it is within the chloroplast that…

They don’t provide energy like the nutrients mentioned above. They are essential to ensure the body is working properly. There are 13 essential vitamins. Vegetables and fruits are two excellent sources for vitamins. Vitamins help with metabolism and digestion, like the nutrients above they help your body grow and develop. When a person is ill, vitamins are a great way of strengthen the immune system and helping fight the illness that’s why it is important to get regular amounts of vitamins…

Lipids are fatty acids and their derivatives, and substances related biosynthetically or functionally to these compounds. Lipids are diverse group of organic compounds including fats, oils, hormones, and certain components of membranes that are grouped together and mainly amphipathic. The variation in head groups and aliphatic chains allows the presence of more than 1000 different lipid species in any eukaryotic cell. Different types of lipid include Phospholipids, Sphingolipids and Cholesterol…

In RBCs, G6PD is the only enzyme which protect against oxidative damage.12, 45 RBCs continuously contact with oxidants as free radicals produced by conversion of oxyhaemoglobin to deoxyhaemoglobin and peroxides generated by phagocytosing granulocytes;46 here NADPH is the most important factor used to protect against oxidants. RBCs in normal individuals can activate NADPH generation in response to oxidative stress but not in G6PD deficient patients. G6PD deficiency leads to failure in protecting…

values of serum urea concentration in all Volunteers. The liver is the most important organ, which play a pivotal role in regulation of various physiological processes in the body. It is involved in several vital functions, such as metabolism, secretion and storage. It has great capacity to detoxicate toxic substances and synthesized useful principle (10) .When liver cell membrane is damaged a variety of enzymes located normally in cytosol is released into the blood, thereby,…

Pathophysiology In metabolic syndrome many organs are affected due to malnutrition, stress and inactivity. With all these factors playing a part the body has different ways of trying to protect it self, that in turn can cause more harm than good. Abdominal obesity, insulin resistant, hypertension, and chronic cortisol release are results of the factors which contribute to metabolic syndrome. Abdominal Obesity A high consumption of calorie dense food and lack of physical activity are…

choice for this investigation. It has been shown in many studies such as the article “HdeB chaperone activity is coupled to its intrinsic dynamic properties” very recently published in the prestigious magazine Nature that bacterial growth and overall metabolism can be inhibited by alterations in the pH of the culture. The active ingredient hypochlorous acid, found in bleach, affects proteins in bacteria by changing the pH of the environment and therefore denaturing them by affecting their…
